* Tests that if calls to XPCOM functions return the same object, then
* the Javaconnect interface creates the proper Java proxies.
* <p>
* The XPCOM call to <code>nsISupports supp = entries.getNext()</code> returns
* an object, for which we create an <code>nsISupports</code> Java proxy. Then,
* the XPCOM call to <code>supp.queryInterface(nsIFile.NS_IFILE_IID)</code>
* will return the same object (same address). Javaconnect needs to be smart
* enough to create a new <code>nsIFile</code> proxy, rather than reusing the
* <code>nsISupports</code> one that was previously created.
